Abstract
A procedure for the preparation of new bases of 4,5-dihydro-2-alkoxycarbonylamino-4-aryl-imidazoles of formula: *** (See formula I) where R is lower alkyl; one of R1 or R2 is hydrogen, hydroxy, lower alkyl, lower alkoxy, fluorine, chlorine, bromine, iodine or trifluoromethyl and the other is hydrogen, or the same group as the other of R1 or R2 and where R1 or R2 may be at any different position on the phenyl ring or R1 or R2 together they form methylenedioxy and are on adjacent carbon atoms in the phenyl ring, the method of which is to react a pharmaceutically acceptable hydrogen ion addition salt of a compound represented by said formula (I) with an organic or inorganic base for a period of time sufficient to convert substantially all the mentioned addition salt into the corresponding free base.
